"I recently celebrated my seven-year anniversary working on Diablo III, and while it's been one of the most challenging and rewarding periods of my life, I've reached a point creatively where I'm looking forward to working on something new. The powers that be at Blizzard have been gracious enough to give me that opportunity. Over the course of the next several weeks, I will be moving off of the Diablo III project and transitioning elsewhere within Blizzard. This decision was not an easy one for me, and not one I made quickly, but ultimately it's what I feel is right."

Wilson also assured fans that the decision "will not negatively impact our ongoing support of Diablo III" and went on to detail some of the patches and improvements that will be implemented in the game in the coming weeks.

He also acknowledged some of the fallout from the game's less-than-solid launch, saying, "I know some of you feel we fell short of our promise to release the game 'when it's ready.' While we're not perfect, we try to make the best decisions we can with the information and knowledge we have at the time. That doesn't mean we always make the right decisions, but if we made a mistake then I feel we've made an exceptional effort to correct it. This is what you can always count on from Blizzard: that we will stand by our games and make every effort to continually improve them over time."

Wilson ended by saying that Diablo fans were "the most passionate, dedicated group of gamers a designer could hope to have."

The post did not specify what his new role at Blizzard would be or what future projects he would be working on.
